nRF52832 Questions about the Analog to Digital Convertion

[Gagan Gopal]

I was looking at the nRF52832 used for Bluetooth modules. And I was trying to understand the Analog to Digital converter in the nRF52832. I was wondering if anyone had or knew the circuitry diagram of the Analog to Digital converter and knew how much power it consumed for its conversion. Thank You.

Did you study the section in the Product Specification about it ... ?

There's certainly a block diagram there

Yes I just saw it. I was able to find the power consumption I think. It said the current drawn from the Analog to Digital converter during conversion is 260 micro amperes. I assume that is how much power the Analog to Digital converter uses during conversion.

Also, I looked through the product specification sheet and could not find a block diagram or a circuit diagram of the Analog to Digital converter. 

Also, I saw the input range and was wondering what is the input range of voltage so that it can be converted in the Analog to Digital converter. I think it said 0.83-1.3 V but it is not clear.

Perhaps you were just looking at the Product Brief ... ?
